Making HTTP requests with curl to real internet websites and trying different headers is my favourite way to play around with HTTP & learn.
curl tips:
-ishows the response headers-Ishows the response headers (by sending a HEAD request)-Hadds a request header
Try the Range header:
curl -i https://examplecat.com/cat.txt -H "Range: bytes=8-17"
Request (and print out!) a compressed response:
curl -i https://examplecat.com
-H "Accept-Encoding: gzip" -- output -
Get a webpage in Spanish:
curl -i https://twitter.com -H "Accept-Language: es-ES
Get redirected to another URL:
(hint: look at the Location header!)
curl -i http://examplecat.com
Guess what content delivery network Github iS using:
(hint: it’s in a header starting with x—)
curl -I https://github.githubassets.com
Find out when example.com was last updated
(hint: Last—Modified)
curl -I example.com
Get a 404 not found:
curl -i examplecat.com/bananas
